Microduck Review: $399 Robot Specs and Verdict
This Microduck review covers Pollen Robotics' $399 biped, its learning stack, preorder risks and who should wait for independent tests.
This Microduck review finds a focused $399 learning platform for developers who want to train legged movement, not a household robot. Pollen Robotics supplies an assembled biped, and Hugging Face Jobs offers a cloud training route. Yet buyers must preorder before independent testing, final specifications or retail service history exist.[1][2][3][5]
This is a documentary review, not a hands-on test. We assessed Pollen's product pages and launch materials. They contain no independent durability, battery or locomotion benchmark for a shipping retail unit.[1][2][3]
We also reviewed the two public code repositories. They contain no results from independent tests on retail hardware.[4][5]
What are the Microduck specs and package contents?
The $399 Microduck package includes the assembled robot, one removable battery, a USB-C cable and a game controller. Its 15 motors drive the legs, head, neck and beak. A Rockchip RK3566 processor with an AI accelerator runs beside 1 GB of RAM and 32 GB of storage.[1][2]
Its sensor set includes a front camera and two inertial sensors. An 8 by 8 time of flight matrix measures range. Microduck also has microphones, a speaker, Wi-Fi, Bluetooth and two NFC antennas.[1][2]
| Specification | Published value | Evidence status |
|---|---|---|
| Height and width | 25 cm by 14 cm | Manufacturer specification.[1] |
| Weight | Under 800 g | Manufacturer specification.[1] |
| Actuation | 15 degrees of freedom across the legs, head and neck | Manufacturer specification.[1] |
| Compute | Rockchip RK3566 with AI accelerator | Manufacturer specification.[1][2] |
| Memory and storage | 1 GB RAM and 32 GB storage | Manufacturer specification.[1][2] |
| Range sensing | Compact 8 by 8 time of flight matrix | Manufacturer specification.[1][2] |
| Battery | Removable 2600 mAh NP-F550, around one hour depending on use | Vendor estimate without a published test method.[1][2] |
| Software | Apache 2.0 SDK, simulation and training tools | Source code and training repository are public.[1][4][5] |
| Retail price | $399 before taxes and shipping | Current US preorder price.[2] |
Pollen says the robot ships with seven trained moves. Its published demonstrations cover walking, sitting and standing, kicking, grabbing with the beak, roller skating and recovery from common falls.[1][3][4] These are manufacturer demonstrations. They show the intended behavior set, not repeatability across retail units.
Our view: Microduck earns its place on a workbench through an inspectable training path, not through the number of tricks in its launch reel.
How does Microduck reinforcement learning work?
Microduck's reinforcement learning stack is the main reason to buy it. Its runtime drives the servos with neural policies through a 50 Hz control loop. The separate training repository uses MuJoCo and PPO, models randomized conditions and backlash, then exports ONNX policies for the robot to run.[4][5]
That public path from training environment to runtime is useful evidence.[4][5]
A buyer can inspect the software before ordering.[4][5]
The local training quickstart requires a CUDA GPU, though the project also supports Hugging Face Jobs for users without one.[5]
"Open source" needs a qualifier here. Pollen says the software stack is open under Apache 2.0, while the mechanical and electronic design files are not open source.[1] Microduck is therefore an open software platform built on closed hardware.
What are the Microduck preorder risks?
Microduck remains a preorder with a changing delivery estimate and unfinished specifications. Pollen Robotics opened orders on 27 August 2026 and first targeted deliveries before Christmas. Its store now says new orders may take 4 to 6 months and cannot promise Christmas delivery.[1][2][3]
Pollen has not finalized the camera resolution, field of view or range sensor reach. Radio versions, SDK language coverage and the recommended minimum age are also unsettled.[1] Those gaps weaken a purchase case built around computer vision or classroom use.[1]
Long-term reliability is unknown because retail units have no public service history.[1][2]
For the same evidence test at larger scales, read our reports on the XPENG IRON production line and humanoid robots in warehouses.
Pollen sells a $119 developer pack with three spare motors, five motor cables, two batteries, a dual charger and tools. The runtime also supports verified updates and rollback.[1][4]
Those provisions may make repairs and failed updates easier, but neither establishes component life or support turnaround.[1][4]
*Scores are Robotsider editorial calls based on the cited documents, not measurements from tests. Low evidence scores reflect missing independent tests, retail service history and final safety information.*
Pros
- The $399 base package includes an assembled robot, battery and controller.[2]
- The runtime, simulator and reinforcement learning tools are available for inspection before hardware ships.[1][4][5]
- Owners can replace the NP-F550 battery and buy optional spare parts.[1]
Cons
- New orders have a 4 to 6 month estimate, replacing the original Christmas target.[1][2]
- Battery runtime is a vendor estimate, and no independent movement benchmark is available.[1]
- Camera, range sensor, radio, SDK language and recommended age details are not final.[1]
Microduck vs Reachy Mini Lite: which should you buy?
Microduck and Reachy Mini Lite both cost $399 in the United States, but they teach different parts of robotics. Microduck is an untethered biped for learned movement and policy transfer. Reachy Mini Lite is a stationary kit for expressive interaction, vision, audio and desktop applications that needs a connected computer.[2][3][5][6]
| Decision point | Microduck | Reachy Mini Lite |
|---|---|---|
| Best fit | Legged movement, reinforcement learning and sim to real experiments.[3][5] | Expressive interaction, vision, audio and desktop applications.[3][6] |
| Mobility | Untethered biped with 15 motors.[1][2] | Stationary body with nine servos and six degree of freedom head motion.[6] |
| Compute | RK3566 onboard computer.[1][2] | Requires a computer connected over USB-C.[6] |
| Sensors | Camera, two IMUs, 8 by 8 time of flight sensor, microphones and NFC.[1][2] | Camera, four microphone array and speaker.[6] |
| Assembly | Assembled robot with controller included.[2] | DIY kit; Pollen supplies tools and instructions.[6] |
| US price | $399 before taxes and shipping.[2] | $399, with duties calculated at checkout.[6] |
Choose Microduck if the work starts with gait, balance, recovery or policy transfer.[3][5]
Choose Reachy Mini Lite if it starts with speech, expression or desktop interaction.[3][6]
Neither product is a general household robot.[2][3][6]
Is Microduck worth $399?
Microduck is worth considering at $399 for developers and classrooms that can treat the first batch as part of the experiment. Its assembled form and inspectable training stack lower the entry cost for physical reinforcement learning, but delivery, durability and finished safety details remain unproven. Independent task results are not available.[1][2][4][5]
Anyone who needs proven uptime, fixed delivery or a finished safety case should wait.[1][2]
For a buyer who wants a small physical reinforcement learning platform, the $399 preorder is unusually accessible.[1][2][5]
That conclusion comes from documentary evidence, not hands-on use.
